This comprehensive study offers a balanced assessment of libertarian accounts of free will. Bringing to bear recent work on action, causation, and causal explanation, Clarke defends a type of event-causal view from popular objections concerning rationality and diminished control. He subtly explores the extent to which event-causal accounts can secure the things for the sake of which we value free will, judging their success here to be limited. Clarke then sets out a highly original agent-causal account, one that (...) integrates agent causation and nondeterministic event causation. He defends this view from a number of objections but argues that we should find the substance causation required by any agent-causal account to be impossible. Clarke concludes that if a broad thesis of incompatibilism is correct--one on which both free will and moral responsibility are incompatible with determinism--then no libertarian account is entirely adequate.

This article contends that recent attempts to construct Frankfurt-style cases (FSCs) are irrelevant to the debate over free will. The principle of alternate possibilities (PAP) states that moral responsibility requires indeterminism, or multiple possible futures. Frankfurt's original case purported to demonstrate PAP false by showing an agent can be blameworthy despite not having the ability to choose otherwise; however he admits the agent can come to that choice freely or by force, and thus has alternate possibilities. Neo-FSCs attempt to (...) show that alternate possibilities are irrelevant to explaining an agent's moral responsibility, but a successful Neo-FSC would be consistent with the truth of PAP, and thus is silent on the big metaphysical issues at the center of the free will debate.

Rogers canvases the literature critical of recent experiments, adding new criticisms of her own. She argues these experiments should not undermine belief in human freedom and lists ethical and practical problems facing the attempt to study free will experimentally.

This article demonstrates that there is no free will problem in forensic psychiatry by showing that free will or its lack is not a criterion for any legal doctrine and it is not an underlying general foundation for legal responsibility doctrines and practices. There is a genuine metaphysical free will problem, but the article explains why it is not relevant to forensic practice. Forensic practitioners are urged to avoid all usage of free will in their forensic (...) thinking and work product because it is irrelevant and spawns confusion. (shrink)

Is it consistent to maintain that human free will is incompatible with determinism in the natural world while also maintaining that it is compatible with divine universal causation? On the face of it, divine universal causation looks like a form of determinism. And the intuitions which lead to incompatibilism about free will and natural determinism also lead to incompatibilism about free will and divine determinism. Several thinkers have attempted to resist this conclusion. This essay critiques that view, (...) with a special focus on how it is developed in the work of W. Matthews Grant (2016, 2019). Grant contends that we can understand all of God’s activity as an exercise of divine “libertarian” free will and can construe God’s actions as nothing over and above the (created) effects brought about. I argue that Grant’s attempted reconciliation of human free will and universal divine causation fails, and on two counts. First, Grant does not succeed in presenting an account of the interaction of divine agency and created agency which avoids occasionalism; second, even if we assume Grant’s account successfully avoids the charge of occasionalism, it fails to reconcile divine agency with created free agency. The latter is illustrated by exploring the nature of the determination relation required by incompatibilist, agent-causation based accounts of free will. (shrink)

This article has two aims: to articulate the main lines of argument for Libet's and Wegner's theses, and to survey philosophical responses in the present century to the argumentation. Because a proper understanding of the scientific argumentation at issue requires attention to a raft of data and the experiments that generate them, reasonable constraints on space preclude discussion of philosophical responses before 2000.

In this paper I criticize libertarianism and skepticism about free will. The criticism of libertarianism takes some steps towards filling in an argument that is often mentioned but seldom developed in any detail, the argument that libertarianism is a scientifically implausible view. I say "take some steps" because I think the considerations I muster (at most) favor a less ambitious relative of that argument. The less ambitious claim I hope to motivate is that there is little reason to believe (...) that extant libertarian accounts satisfy a standard of naturalistic plausibility, even if they do satisfy a standard of naturalistic compatibility. The argument against skepticism about free will tries to show (1) perhaps the most prominent form of skeptical argument against the existence of free will does not work, and (2) there is a good general argument against skepticism about free will.

One has it that earlier circumstances and the laws of nature uniquely determine later circumstances, and the other has it that past present and future all exist tenselessly in a ‘block universe,’ so that the passage of time and associated changes in the world are illusions or at best merely apparent.

I agree with much of Habermas's article ?The Language Game of Responsible Agency and the Problem of Free Will,? but concentrate on disagreements. (i) He is wrong to think the language game of neuroscience is somehow at odds with the language game of rational intentionality. I argue that they give different levels of description of the same system. He also has too narrow a conception of contemporary neurobiological research. (ii) He is mistaken in thinking there is a ?performative contradiction? (...) in engaging in research that presupposes free will in order to disprove free will. (iii) His ?epistemic dualism? is irrelevant to the issue. (iv) He has some misconceptions about the world in general, especially about ?downward causation.? He seems to think that the physical world is deterministic. It is not. Quantum indeterminacy pervades the entire universe. We have the illusion of determinism because in some systems the quantum indeterminacies cancel out at the macro level. Is the brain a deterministic system? Right now we do not know. (shrink)

Kant famously insists that free will is a condition of morality. The difficulty of providing a demonstration of freedom has left him vulnerable to devastating criticism: critics charge that Kant's post-Groundwork justification of morality amounts to a dogmatic assertion of morality's authority. My paper rebuts this objection, showing that Kant offers a cogent demonstration of freedom. My central claim is that the demonstration must be understood in practical rather than theoretical terms. A practical demonstration of x works by bringing (...) x into existence, and what the demonstration of freedom brings into existence is a moral will, a will regulated by the moral law and capable of acting in accordance with it. Since to act morally is to act freely, bringing a moral will into existence actualizes our capacity for freedom and demonstrates that we possess it. To confirm the viability of such a demonstration, Kant must establish that agents can regulate their wills by practical principles, and that practical judgments are efficacious of themselves (i.e., that non-Humean motivational internalism is true). Kant, I argue, is successful on both counts. (shrink)

I remember applying for the master’s in bioethics program at the University of Pennsylvania and thinking very carefully about what I wanted any reader to know about my childhood and its impact on shaping my career path to this point.

Some people endorse a view called incompatibilism, which states that free will is incompatible with determinism. No free action could possibly be determined, they think. More informatively, incompatibilists think it is impossible that someone’s freely acting be causally guaranteed to happen by things that occur before she freely acts. Some people hold a view called libertarianism, which states both that incompatibilism is true and that someone actually performs a free action. Other people reject incompatibilism. They hold to (...) compatibilism, which is the view that it is possible that previous happenings in the world could absolutely causally guarantee—that is, could cause in a deterministic way—that someone freely acts. In this chapter, I argue that libertarianism is, for the time being at least, the most sensible view. (shrink)

How does the term ‘free will’ refer? This question seems to lie at the center of debates about whether the attitudes and practices that depend on our successful attributions of basic-desert-entailing moral responsibility ought to be preserved or eliminated. In this paper I tackle questions about the way that different reference-fixing conventions might inform disagreement between preservationists and eliminativists about free will and moral responsibility, and argue that even recent elimination-friendly work on reference fails to offer much real (...) support for eliminativism. In fact, making explicit the role that different motivating concerns play in rendering certain reference-fixing conventions operative for eliminativists and preservationists suggests at least one powerful reference-based argument in favor of preservationism.

Imagine we are at a murder trial. Randy Smith is accused of killing his Aunt Millie. The defense admits that on the night of the murder, Smith had an argument with his Aunt, that he took a pistol out of his jacket and shot her. She died of the gunshot wound. Smith knew that the gun was loaded, that Millie was directly in front of it, and that he was pulling the trigger. He was not insane at the time, there (...) were no abnormal chemicals in his brain, and he was not acting in self-defense. He killed her knowingly, intentionally, and unjustifiably. (shrink)
